PUMA Series

The PUMA Series is DN Solutions (formerly Doosan Machine Tools) high performance lathe series. Designed for heavy and intermittent cutting, accurate production, and premium surface finishes, this series has a wide variety of models with chuck sizes ranging from 8”-21”, turning lengths up to 120", and options for sub-spindles, y-axis, and milling capabilities. This Series has a box guideway structure which prevents vibration and gives it secure dynamic rigidity. It has the highest spindle speed in its class and also delivers powerful cutting capabilities.

What Makes the PUMA 3100L a Standout Turning Center?

Engineered for rigidity, power, and long-part accuracy.

The DN Solutions PUMA 3100L is designed for manufacturers who require high-accuracy, long-bed machining with uncompromising surface quality. Its 30° slant-bed construction, box-way design, and powerful 30 HP spindle deliver consistent precision even in heavy-duty roughing operations. Combining a FANUC 0i-Plus control, EZ Guide i conversational interface, and fast 1,181 IPM rapid traverse, this lathe minimizes non-cutting time while maintaining micron-level repeatability.

Performance Highlights

2,800 RPM spindle speed with 828 ft-lb torque
50.4″ max turning length and 20.7″ max diameter
4.0″ bar capacity for large stock
10-station turret with 0.15 s index time
FANUC 0i-Plus control with iHMi touchscreen and EZ Guide i

How Is the PUMA 3100L Built for Power, Stability, and Longevity?

Precision construction reduces vibration, heat, and setup time.

The one-piece Meehanite® cast-iron bed resists thermal distortion and twisting, ensuring long-term accuracy. Its wide rectangular box-ways, induction-hardened and resin-bonded, minimize friction and improve damping for superior surface finishes. Large-diameter ball screws are directly coupled to AC servos to eliminate backlash, while torque-detection sensors protect the axis drives from collision damage by instantly reversing servos on overload.

Engineering Advantages

Meehanite® slant-bed casting for rigidity and chip flow
Triple-row front bearings, double-row rear bearings for spindle stability
Electric torque limiter and auto-reset protection
Servo-driven turret and tailstock for precision movement

What Advanced Features Improve Usability and Accuracy?

Smart controls, tool monitoring, and automated systems boost productivity.

Equipped with FANUC 0i-Plus and a 15″ touchscreen, the PUMA 3100L simplifies operation with EZ Guide i conversational programming. Operators can mix G-code and menu-based inputs, visualize cycle paths, and monitor tool loads in real time. The Easy Operation Package (EOP) includes tool-life tracking, alarm guidance, and automatic offset correction to reduce errors during setup.

Control Highlights

Conversational and G-code hybrid programming
Tool load monitor with automatic shutdown
Alarm and parameter libraries for quick troubleshooting
Ethernet, USB, and RS-232C connectivity
1,000-program storage capacity with multi-language support

How Does the Cooling and Heat Isolation System Enhance Accuracy?

Smart coolant design and thermal control for consistent precision.

The multi-stage 65 PSI coolant pump flushes chips directly from the cutting zone. Optional 145 PSI or 1,000 PSI packages improve chip evacuation, deep-hole drilling, and surface finish quality. A roller-mounted 70-gallon coolant tank, separated from the bed, prevents heat transfer. Heat-isolation covers and exhaust fans dissipate thermal buildup, while an auto light-off function further reduces ambient temperature.
